Properly connecting an unmanaged switch to a Cisco 2960

I'm having DHCP issues when connecting an unmanaged switch to my Cisco 2960 switches.  I have the port it is connected to set to access VLAN1 which is the native vlan for all traffic.  Some computers are able to connect and receive DHCP perfectly.  A static IP printer is also running off the unmanaged switch and is able to be accessed from all parts of the network.  I have statically assigned IP's to those computers that do not receive an IP and I'm able to ping any PCs connected to the unmanaged and I'm not able to ping internet domains or the file servers upstream from the unmanaged switch.  I'm guessing that multicasting is not travelling back up to the 2960 from the unmanaged switch.  I need a little help in understanding how to set up the 2960 to communicate properly with the unmanaged switch.  

The unmanaged switch is an SMC 10/100.  I need to get this running temporarily until i'm able to run homeruns back to the computer room into a newly acquired space.

You should be able to simply set the 2960 port to switch mode access and be done with it.
That will set to vlan 1 as native, untagged.
You might have a duplex mismatch.
Check the duplex on the 2960 that is negotiated. The port needs to be set to auto and not 100/full.
on the switch port connected to the smc do

switchport mode access
switchport access vlan 1 (just to make sure)
switchport no nonegotiate (is should run at the speed and duples of the smc)
switchport no shut

Speed and duplex are both auto, as are all ports.  This is the port setup below.  1 machine will take DHCP on that unmanaged switch and anything plugged in after will not.  I can set IP on machines to static but they will not ping past the unmanaged switch, only to things connected to the unmanaged switch.  I can't ping from the Cisco down to those things i set to static, only to the one computer that received the DHCP.  It almost seems like the Cisco doesn't know the route to anything on that port except the first one assigned.

OK so after looking through configurations of the switch ports, which the previous network admin set up, I find that each port has "port-security maximum 2" set on it.  Changed to 10 and now devices work.  Previous admin had limited devices per port to 2 devices.
